[0002] Used in automotive air suspension and active suspension systems, the function of a vehicle height sensor is to detect the vehicle's height (the relative displacement between the vehicle body and the lower suspension arm or shock absorber support in the vertical direction). Photoelectric sensors are typically used; the sensor body is mounted on the vehicle body to measure the suspension. However, photoelectric sensors are expensive and difficult to maintain. Currently, in the automotive industry, to improve ride comfort and handling stability, various sensors are installed at appropriate locations on the vehicle to collect attitude data during operation, ultimately controlling and adjusting the vehicle's operating state. A vehicle height sensor is one such height detection sensor mounted on the vehicle body. Existing automotive height sensor electronic systems consist of several circuits, including A / D conversion, MCU, communication ports, and power processing. The overall circuitry is complex, has low reliability, and is costly. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Due to the complex circuit structure, high maintenance difficulty, and low reliability of existing technologies, please refer to [the relevant documentation / reference]. Figure 1 - Figure 6 This embodiment proposes a vehicle height sensor electronic system, which can significantly simplify the circuit structure, reduce the difficulty of circuit maintenance, and improve the reliability of the circuit system. The system includes an interface module 2, a microprocessor module 1 for detecting changes in vehicle height, and a power supply module 3 for providing power to the microprocessor module 1. The microprocessor module 1 consists of a sensing chip and a surface-mount capacitor C1. The sensing chip is grounded through the surface-mount capacitor C1, and the VDD interface of the sensing chip is connected to the interface module 2. The power supply module 3 consists of an external power supply, a transformer, a rectifier circuit, and a current-limiting resistor R1. The transformer converts the voltage of the external power supply into a voltage to be rectified, the rectifier circuit converts the voltage to be rectified into a stable voltage signal, and the current-limiting resistor R1 provides stable power to the microprocessor module 1. The interface module 2 consists of interface 1, interface 2, and interface 3. Interface 3 is connected to the VDD interface of the sensing chip, which is model AS5172.

[0026] The magnet mechanism 6 changes with the vehicle height, and the magnet 62 in the magnet mechanism 6 rotates during the change in vehicle height. This causes the magnetic flux sensed by the microprocessor module 1 to change in strength. The microprocessor module 1 then converts the sensed magnetic flux into an electrical quantity whose magnitude also changes with strength. Finally, the microprocessor module 1 converts the sensed electrical quantity into electrical parameters, performs analog and digital processing, and finally generates vehicle height data, which is then transmitted through the power supply port. The power supply pin of the sensing chip is also the signal output pin. By using a simplified microprocessor module, vehicle height detection can be achieved while effectively reducing the number of electronic components used. At the same time, the reliability and detection accuracy of the entire system are improved, and the cost is reduced by 30%. This reduces the manufacturing cost of the electronic system and significantly reduces the difficulty of maintenance, resulting in extremely significant social benefits.

[0027] The sensor electronic system also includes a circuit board 4, a chip assembly 5, and a magnet mechanism 6. The chip assembly 5 includes a sensing chip 51 for sensing changes in magnetic flux of the magnet mechanism 6. A surface-mount capacitor 52 is fixedly connected to the side of the sensing chip 51 to save space and filter electrical signals from the power module 3. The circuit board 4 includes a base plate 41. The side of the base plate 41 has multiple limiting holes 42 for limiting and fixing the base plate 41. The top surface of the base plate 41 has multiple interface holes 43 for soldering wires. The magnet mechanism 6 includes a magnet connecting rod 61. A magnet 62 for generating changes in magnetic flux is fixedly connected to the bottom of the magnet connecting rod 61.

[0028] In this invention, magnet 62 is fixed to the bottom end of magnet connecting rod 61. When magnet 62 is within a suitable distance from the Hall element inside chip assembly 5, sensing chip 51 can sense the magnetic force of magnet 62. Magnet 62 has north and south poles, so its magnetic force changes when it rotates or its height changes. Therefore, when the height of the car changes, chip assembly 5 connected to the car also rotates, which in turn drives magnet 62 to rotate. As magnet 62 rotates, the magnetic force sensed by sensing chip 51 also changes. Sensing chip 51 converts the strength of this magnetic force into the strength of an electrical signal, which is output through the circuit of circuit board 4. Through the coordinated operation of sensing chip and magnet mechanism, the change in magnetic flux of magnet at the bottom of magnet mechanism can be detected, and the chip assembly is limited by limiting hole, which not only ensures the safe and stable use of the chip, but also accurately measures the vehicle height, improving the safety, stability, and detection accuracy of the vehicle body measurement chip.

The power supply is also common knowledge in the field.
